Malloc a 3-Dimensional array in C?

Question

I\'m translating some MATLAB code into C and the script I\'m converting makes heavy use of 3D arrays with 10*100*300 complex entries. The size of the array also depends on t

Answer 1

This should work, you are not typecasting the return value of malloc

#include 

int main () {
  int ***array = (int ***) malloc(3*sizeof(int**));
  int i, j;

  for (i = 0; i < 3; i++) {
    array[i] = (int **)malloc(3*sizeof(int*));
    for (j = 0; j < 3; j++) {
      array[i][j] = (int *)malloc(3*sizeof(int));
    }
  }

  array[1][2][1] = 10;
  printf("%d\n", array[1][2][1]);
  return 0;
}
